ADJUSTABLE CLAMPING MEANS FOR SHOESHINE FIXTURES Filed Jan. 20, 1947 v b77765 Nev-fr;

toward the toe part of the shoe rest. Accordingly the heel plate is brought into firm clamping engagement with the shoe heel. The spring accommodates any necessary yielding of the applied force. In the use of the fixture it is only necessary to throw the lever downwardly to the position, indicated in dash lines in Fig. 7, to clamp a shoe. To release the shoe the lever is thrown upwardly to the lateral position shown in full lines in Fig. 7. A spring 25 is employed to return the rod, and this spring need only be comparatively light in applied stress.

The fixture is preferably supplied with a screw clamp so devised that it can be used to attach it to either a vertical or horizontal support, as for instance the back or seat of a chair. The

4 with said heel plate adapted to have clutching engagement with said rod when in an oblique position whereby to connect said heel plate thereto so that it is held against relative backward displacement.

3. A shoeshine fixture comprising a support providing a sole plate having spaced ears for wedging engagement with the toe portion of a shoe, a heel plate slidable lengthwise of said support having a part for abutment with the back of the shoe heel, a rod mounted to slide longitudinally on said support, a clutch plate extended downwardly and forwardly from said heel screw clamp is comprised of a U-shaped clamp, denoted as a whole by the reference character A,

having a thumb screw 26 threadedly carried by one of its legs, 21, for tightening against a supporting member engaged with the opposite leg 28. The leg 28 is provided with a male element 29 of a dovetail joint and the back 30 is provided with a similar male element 3i The female element of the dovetail is supplied on the bottom of the support In to extend horizontally thereof and is denoted at 32. The said male and female elements are tapered through their lengths and the taper of the female element extends rearwardly of the support In so that either of the male elements may be slid therein with a rearward movement. As shown in Fig. 2, to use the screw clamp for connecting the fixture to a vertical support, such as the back B of a chair, the dovetail connection is made with the male element 3 l When it is desired to attach the fixture to a horizontal support such as the seat of a chair the screw block is changed to a position at right angles to that shown in Fig. 2 by using the male. element 29. An important feature is that the lever is utilized to prevent the screw clamp from becoming inadvertently detached while the fixture isbeing used. To this end the lever is provided with a detent lug 33 arranged to overlie and contact the frontal surface of the screw clamp when the lever is swung to a looking position as best shown in Fig. 6. When the lever is swung aside to a non-locking position the screw clamp is unobstructed and can be readily removed if need be.

Having described the selected embodiment of the invention it will be understood that such changes and variations may be resorted to as come within the ensuing claims.

What I claim is:

1. A shoeshine fixture comprising a support providing a sole plate having spaced ears for wedging engagement with the toe portion of a shoe, a heel plate slidable lengthwise of said support having a part for abutment with the back of the shoe heel, a rod mounted to slide longitudinally on said support, a clutch plate slidable with said heel plate adapted to have binding engagement with said rod when in an oblique po-. sition whereby to retain said heel plate against backward movement, and a manual device for drawing said rod forwardly to effect clamping of the shoe.

2. A shoeshine fixture comprising a support providing a sole plate having spaced ears for wedging engagement with the toe portion of a shoe, a heel plate slidable lengthwise of said support having a part for abutment with the back of the shoe heel, a rod mounted to slide longitudinally on said support, a clutch plate rigid plate with a hole in it through which said rod passes to retain the heel plate against backward movement by a clutching engagement, and a manual device for drawing said rod forwardly to effect the clamping of the shoe.

41A shoeshine fixture comprising a support providing a sole plate having spaced ears for wedging engagement with the toe portion of a shoe, a heel plate slidable lengthwise of said support having a part for abutment with the back of the shoe heel, a rod mounted to slide longitudinally on said support, a clutch plate on said heel plate having an aperture through which said rod extends to provide clutching engagement therewith when the clutch plate is in a backwardly tilted position, anda lever mechanism for drawing said rod forwardly to effect clamping of the shoe.

5. A shoeshine fixture comprising a support providing a sole plate having spaced ears for wedging engagement with the toe portion of a shoe, a heel plate slidable lengthwise of said support having a part for abutment with the back of the shoe heel, a rod mounted to slide longitudinally on said support, a clutch plate on said heel plate having an aperture through which said rod extends to provide for clutching engagement when the clutch plate is in a backwardly sloped position, and a cam lever adapted to draw saidrod forwardly to eifect clamping of the shoe.

6. A shoeshine fixture comprising a support providing a sole plate having spaced ears for wedging engagement with the toe portion of a shoe, a heel plate slidable lengthwise of said support having a part for abutment with the back of the shoe heel, a rod mounted to slide longitudinally on said support, a clutch plate rigidly carrying said heel plate and extended downwardly and forwardly therefrom, said clutch plate having an aperture through which said rod passes to retain the heel plate against relative retrograde movement by a clutching engagement. a lever pivoted on said rod to swing about the axis thereof to a locking position and having a cam face about its fulcrum engaged with a cam surface on said support for imparting forward movement to the rod when the lever is thrown to its locking position, andabutment means connecting the lever to the rod for transmitting such forward movement to the rod to-effect the clamping of the shoe.

'7. In a shoeshine fixture, a support for a shoe, a screw clamp for attaching said support to a relatively non-movable support, an interfitting connection for attaching said screw clamp to said support, said interfitting connection consisting of a female member on said support and a male member onsaid screw clamp, said members being engageable by a sliding action; means for clamping a shoe on said support including a lever adapted to be thrown to a locking position, anda detent device carried by said lever to engage The following references are of re'cord the file of this patent:
